Anti-bacterial Effects of Aquatic and Chloroformed Eextract of Allium Sativum on E. coli

E. coli bacteria is one of the most important infection factors in mankind and also، by increasing the resistance of bacteria against chemical drugs and low side effects of herbal drugs، today the herbal ones are evaluated by researchers. The aim of the current study is considering the anti- bacterial aquatic and chloroformed effects of Allium Sativum on E. coli. In this study، first the aquatic and chloroformed extraction of Allium Sativum was prepared، then the MIC and MBC rates of extraction were calculated and the diameter of lack of growing areola of E. coli was measured in different attenuation of extraction. And also، the sensitivity of different anti- biotic was considered by Kirby/baur standard method and the results were analyzed by SPSS software، version 18 and Anova one-way statistical test. The chloroformed extraction with areola diameter average of lack of growing about 27±3% showed more powerful anti-bacterial effects than aquatic extraction with the average of 9±2% and the maximum rate of anti-bacterial sensitivity to Amikacin was showed about 40. 69 %. Although the medical usage of herbal extractions and essences is valuable for their less side effects rather than common medical factors، but it should be done more studies about the mechanism of ingredients of this plant on bacterial factors for the medical usage of anti-bacterial aquatic and chloroformed extraction of Allium Sativum.
